Since the early 1970s Railway vehicles have been using remote control systems. Cattron-Theimeg was one of the first companies to develop and install remote control systems for locomotives and other track-bound vehicles. Until today Cattron-Theimeg sets standards for the safety and the functionality of these radio remote control systems. Due to the exceptional know-how and vast experience of Catttron-Theimeg´s engineers with regard to the safety aspects of locomotive remote controls, the company has been accredited by the Federal Railways Authorities of Germany as a development company for safety applications.
